4 + 7 * 3 = 4 + 21 = 25
3 * 2 + 4 * 5 = 6 + 20 = 26
2 * 12 - 8 : 4 = 24 - 2 = 22
18 - 2 * 3 + 4 = 18 - 6 + 4 = 12 + 4 = 16
(4 + 7) * 3 = 11 * 3 = 33
3 * (2 + 4 * 5) = 3 * (2 + 20) = 3 * 22 = 66
2 * (12 - 8 : 4) = 2 * (12 - 2) = 2 * 10 = 20
18 - (2 * 3 + 4) = 18 - (6 + 4) = 18 - 10 = 8
(4 + 7) * (3 + 4) = 11 * 7 = 77
3 * (2 + 4) * 5 = 3 * 6 * 5 = 18 * 5 = 90
2 * (12 - 8) : 4 = 2 * 4 : 4 = 8 : 4 = 2
18 - 2 * (3 + 4) = 18 - 2 * 7 = 18 - 14 = 4
